It has just occured to me that since C++ is a strongly typed language it should provide intrinsic support for constants of all intrinsic types that is currently we have: 1 // int 1U // unsigned int 1L // long 1UL // unsigned long '\1' // unsigned char -- it is unsigned since only // octal and hex bit patterns are allowed and // by default they are unsigned -- this may be // shakey logic, it may be implimentation dependent // on whether char is signed/unsigned, I admit '\1'L // wide unsigned char -- see above comment "\1" // unsigned char[] "\1"L // unsigned wide char -- w_chart is scheduled to // be an intrinsic type in ANSI/ISO C++ This as I see it leaves room for: 1S // short 1US // unsigned short 1I // int -- this may not be really neccessary! 1UI // unsigned int '\1'S // signed char -- see I'm following the spirit of C // and confusing programmers nicely by using S for both // short and signed! '\1'U // unsigned char '\1'SL // signed wide char '\1'UL // unsigned wide char "\1"S // signed char[] "\1"U // unsigned char[] "\1"SL // signed wide char[] "\1"UL // unsigned wide cahr[] Ofcourse you can always have: (short) 1; // etc and this may be more portable since you can then have: (int16) 1; // etc where you typedef int16, etc to the correct type in some header somewhere which takes care of compiler/OS/machine dependecies, but shouldn't you be able to do the other way if you want? (Can any one send me the appropriate #define macro to convert 1INT32; to 1L or 1 depending on wether long is 32 or 64 bits?) Well just a though for the standards committee after all it shouldn't break any existing code should it?
